West of here the ground buckles up into the bluffs and scrub oak of Palmer Park, and the neighborhoods of Cimarron Hills spread out below it on the flat. Dunn Landscaping & Lawn works that flat — mowing, trimming, edging, and the cleanups that bracket a Colorado growing season at both ends. Gambel oak turns rust in October and holds its leaves late; the grass goes dormant and comes back with a little help. The craft is in the finish: an even cut, a defined border, no windrows of clippings strewn across the walk. A yard done right sits quietly in the landscape, which is the best compliment it can get.
